batch file to search and copy particular file

hi,i have been trying to make a batch file which does the following:1. search all drives for *.jpg,ppt,pptx, pdf and doc and docx files.2. it should not search the folders like "windows" and "program files"3. it should detect the usb drive and copy the files in usb in a folder and hide it.

i would appreciate if anyone can share the batch file or the code for this in DOS.
